ROLL-ADJUSTING MECHANISM.

Specification of Letters Patent.

Patented Mar. 12, 1912.

To all whom 'it may concern.

Be it known that we, FRANK \VAoKnn- MANN, residing at Garrick, andCHARLES ZABEL, residing at Pittsburgh, in the county of Allegheny andState of Pennsylvania, citizens of the United States, have invented ordiscovered certain new and useful Improvements in RolLAdjustingMechanism, of which improvement the following is a specification.

The invention described herein relates to certain improvements in meansfor effecting a longitudinal adjustment of rolls of rolling mills and ishereinafter more fully described and claimed.

In the accompanying drawings forming a part of this specification Figure1 is a sectional view showing one member or leg of a housing, a journalbox for a roll and our improved adjusting mechanism; Fig. 2 is an endelevation of the parts shown in Fig. 1 and Fig. 3 is a sectional view ona plane indicated by the line III-III Fig. 1.

In the practice of our invention the j ournal box 1 is provided as iscustomary, with the edges of the window in the housing 2. The flanges 3forming the outer wall of these grooves, are extended sufficiently farto permit of the attachment thereto of threaded rods 1 on which aremounted the nuts 5. The threads on both rods are right handed and thesaid nuts are adapted to be rotated by means of a pinion 6 mounted on anextension 7 of the journal of the roll. This pinion 6 has a portion ofits periphery toothed for engagement with the toothed portion 8 of thenuts 5. While the pinion 6 may be rotated by any suitable means it ispreferable that radial openings or holes 9 should be formed in itsperiphery for the reception of capstan bars. A cross head is providedwhich engages the roll in such manner that the latter will follow themovements of the cross head imparted thereto by the nuts 5. Thiscross-head is preferably formed of plates 11 and 12 adapted to slideloosely on the 7 and are arranged on opposite sides of the nuts 5. Theinner follower plate may bear directly upon the end of the journal 13 ofthe roll or through the medium of a wearing washer 11 surrounding theextension 7. The outer follower plate is held in position by means of anut 15 screwing onto a threaded stem 16, on the extension 7 and held inposition by lock nut 17. This nut may bear directly upon the followerplate 11 or through a washer 18. As the follower plates 11 and 12,having between them the nuts 5 are held between the end of the journal13 and the nut 15, any rotation of the nuts 5 by means of the pinion (iwill impart a longitudinal ll'lOVell'lOllt to the roll in one or theother direction.

It will be observed that the several parts forming the roll adjustingmeans are so constructed that when it is desired to change the rolls,all the adjusting mechanism will be carried up when the roll and itsjournal box 1 are lifted out of the housing. By removing the nut 15 thefollower plate 11 and the pinion G can be removed and then by screwingoff the nuts 5 the other follower plate can also he slipped offpermitting the removal of the journal box from the roll.

\Ve claim herein as our invention:

1. The combination with a housing, and a roll rotatably supportedtherein and provided with an extension, of abutments upon saidroll-extension, a cross-head confined between said ahutments, and meansfor shifting the cross-head relatively to the housing.

2. The combination with a housing, and a roll rotatably mounted thereinand provided with an extension, of a non-rotatable crosshead adapted toengage said roll-extension, a plurality of threaded rods secured to thehousing, nuts engaging said rods and rotatably connected to thecross-head, and means for simultaneously rotating the nuts and therebymoving the cross-head relatively to the housing.

3. The combination with a housing, and a roll rotatably mounted thereinand provided with an extension, of abutments upon said In testimonywhereof, we have hereunto roll-extension, plates loosely mounted on theset our hands. 0
